Description
Discharge nozzles are designed to direct the discharge of

®
agent using the stored pressure from the cylin-
ders. Ten sizes of nozzles are available. The system design
specifies the orifice size to be used for proper flow rate and
distribution pattern*. The nozzle selection depends on the
hazard and location to be protected. The 180° nozzle is
commonly used when nozzle placement is at the wall.
Standard nozzles are constructed of brass.
An index mark is stamped on the bottom of the nozzle to
indicate the aiming direction.
* Orifice diameter must be specified when ordering nozzle.
